CWM Recovery and External SD card... still no go - Galaxy S III Q&A, Help & Troubleshooting

Hi all,
I've been rooting Android phones (mostly Samsung) and installing CWM etc for as long as one has been able to. This is the first time I've had any major issues.
Issue being, no matter which CWM I install that states it supports external SD on i9300, I still can't install from zip on ext sd, or backup too it, or mount it!!!
Everyone else seems to be able to fine, but for some reason for me, following the same instructions step by step (tripple checked just to be sure) I cannot.
Now I did initially root the device relatively early on in the development stages for it, and installed a criskello rom (v6) about a month ago. Other than that, I've not played around with anything at all. Today I decided I'd try to install a new rom which I'd saved on the device to the external SD. But no, the CWM I had (6.0.1.0 I think) couldn't read ext sd.
Thus, I installed CWM 6.0.1.2 via Odin (following instructions found here: http://forum.xda-developers.com/showthread.php?t=1719744 )
But apparently for some crappy reason I have to be the odd one out, for whom it refuses to work!
Now, just to be sure, i've tried multiple SD cards, all just basic fat format, even reformated them all on the device itself. But nope, it just refuses to work for me!!!
Anyone got any suggestions or am I just doomed to internal memory only?
I'd REALLY like to be able to backup my device before trying new roms

This problem nevf happened to me. I can restore any backup ive saved.
Maybe its a crisckeloRom related problem.

CWM 6 and onwards is known to not play well with external SD's, despite what they say, since the layout is a little bit different in Samsung phones. Try flashing Chainfire's CF-root package, which will provide you with root (of course) and CWM 5, which works well with external SD's. You have my guarantee.
BUT! If your SD card is somehow damaged, nothing will read it properly. Make sure it actually works, and that is has a format your phone understands:
32 GB and up, and running stock Samsung = exFAT
32 GB and up, and running an AOSP ROM = FAT32
Anything less than 32GB = FAT32

Hey,
I have the same issue as fr0dzy. I'm ran Chainfire's CF-root package with CWM 5.5.0.4 and i can't use my ext-sdcard in recovery (to install zips + nandroid backup/restore). My ext is a 64gb card formatted to FAT32 but i can use it when i boot my rom.
Any suggestions would be really appreciated. Thanks.

I'm on a SGS2 Epic4g Touch- same issue. Rooting it everything runs fine, after installing CWM Agat Recovery through mobile Odin I lose access to all apps on Ext SD, something is definitely not playing right with the card. Have you found a work around?
---------- Post added at 10:07 PM ---------- Previous post was at 09:55 PM ----------
This is my first time rooting and running CWM--- is this issue with phones that have both an Ext SD and a internal MMC partition labeled SD? Thanks for any help, guys!

Solved for me!

This last piece of text solved my problem, thank you! I formatted my 2 GB card as FAT32 and installed a custom ROM (4.1.2 Stock) to recover from a broken Ubuntu Touch ROM.
It was a relief!

Unable to make bootable CWM SD, NT is bricked :(

I successfully rooted my Nook Tablet and installed CM 7. However I foolishly applied a zip update that was not compatible and now I'm stuck in a boot loop.
My CWM bootable SD card refuses to work no matter what. I've followed the steps exactly as stated :
1. Using GParted on Ubuntu
2. I selected No-Free space preceding partition while partitioning
3. 50MB
4. FAT 32
5. Boot and LBA flags
6. Copied files
I don't know what to do to to make it work. I've tried all sorts of minor variations in partitioning the card but nothing appears to make the SD card work.
Can someone please help me?
Use Adam Outler's Ubuntu recovery image. He provides step by step instructions on how to unzip the image and transfer it onto the sd card. Have to use linux so if your on a Windows pc, then go grab you a cd or usb bootable copy of Ubuntu. The restoration process takes a while and seems like it hangs in spots but have patience. It takes somewhere around 20 minutes for it to complete but in the end you will be back on stock 1.4.0, safe and sound....Good Luck.
Alright well, I managed to get CWM working. Apparently my SD Card was just fine - I just needed to make sure the NT was plugged into a computer at the same time.
Now my question is : how do I get things working again? I had previously thought that I could simply flash CM 7 again and this would fix the issue, but now I realize that for some reason CWM only read from the 50MB partition from which it booted. Changing the SD card after booting into CWM doesn't work either.
So what do I do? Thanks again..
Nevermind. What I did was pushed the recovery to the internal card so that I didn't need the SD card to boot into recovery. I then reformatted my card and dumped the CM7 zip onto it. Then reflashed CM7. Voila.

Glad to read you got it working.
Just wanted to comment on the above.
You can boot the SD version of cwm then remove the SD card. This is exactly how I installed CM7 That I'm currently running.
It didn't take the first time as cwm didn't read my SD. But after a repartition of the SD csrdz no problems.

I actually tried taking the SD card out, reformatting it and then trying to get it to read but for some reason CWM just doesn't do it. Maybe I should have tried a few more times...

Help: Cant mount my external SD card under ClockworkMod Recovery

Can anybody help me with this?? (apologies - I first posted thisin the 'General' forum and then realised it should have been put into the Q&A section)
ClockworkMod Recovery (v6.0.1.0) will not mount my SD card (SanDisk 64GB Micro SDXC Ultra Card) and posts "Error mounting /external_sd!"
I have successfully rooted my phone (GT-I9300 running the stock I9300XXBLFB at present) by following the various threads on XDA.
I formatted the sandisk SD card by using the S3's menu>settings>storage>format SD Card. The card is then visible when I run the the "My Files" app, showing both the internal /mnt sdcard and my new /mnt extSdCard which shows a total of 59.47GB space.
I subsequently installed the 'ROM Manager Premium v5.0.0.8" app from the Play Store and then flashed "ClockworkMod Recovery 6.0.1.1".
My problem is that when I run ClockworkMod Recovery and select 'Recovery Mode' - 'mounts and storage'/'mount /external_sd' the app wont mount the SD card stating "Error mount /external_sd"
What am I doing wrong. I have searched the forum for similar problems but have drawn a blank unfortunately. Is it a known issue with the SanDisk 64GB Micro SDXC Ultra Card?
I am confused because the "My Files' app can see the card but the ClockworkMod Recovery app cannot.
I am trying to mount the external SD card so that my PC can recognise it and transfer some new downloaded ROMs to it.
A related (or maybe not) issue is that when I open the CWM Manager app it shows the following warning "this version of CWM Manager should be used with CF-CWM .1.1 or newer. It appears that you are running a different recovery. Various features have been disabled."
Help!!!!! Although I registered on XDA in 2006 I have been in the Android wilderness for several years having 'jumped ship' to the iPhone before returning back to the Android fold.
Unfortunately my knowledge isnt what it once was and I need a helping hand.
Thanks in advance to all who take the time to read this.

Recovery - ClockWorkMod (CWM)
A custom CWM 5.5 build is included in CF-Root, taken from this thread. This provides for the ability to install custom ROMs, and do nandroid (full device) backups and restores. Now also support OTA updates, but an OTA update itself will probably remove CWM, so you need re-flash CF-Root after OTA.
Not compatible with ROM Manager ! Use the CWM Manager provided instead (installed by CF-Root automatically)
Util - CWM Manager
My management application for CWM is also installed, see the recovery thread linked above for further details. It allows you to command CWM (install a ROM, make/restore backups, etc) from normally booted Android.
1st of all the cwm version your using is flakey at best with extsdcard support its something that has only been introduced in version 6.0.1.0 and seems to be still giving bother. If you want extsdcard support I would recommend chainfires version which is non touch but vgood extsdcard support.(find it in original android development)
Secondly cwm manager is the app to use with chainfires cwm versions not the other cwm versions flying around.

Thanks for the helping hand JJEgan .. very much appreciated. I am finding the learning curve for Android a bit steep at the mo because of my time spend throwing money at Apple!!
For anyone else who has a similar problem to mine then follow JJEgans link above, download "CF-SGS3-CWM-v5.5-v1.5.zip" to your PC then follow these instructions
* Your phone should not be connected to your PC yet
* Start up Odin3 v1.85
* Click the PDA button, which is located under the Bootloader button
* This opens up a box, all you need to do is locate and select the "CF-SGS3-CWM-v5.5-v1.5.zip" file
* Turn your phone OFF
* Hold Vol Down + Home + Power, it will ask you to cancel or continue ... press the Vol Up button to continue
* This will put the phone in 'download mode' it should say downloading...
* Connect your phone to your PC
* Make sure the Repartition is NOT checked (by default it should not be anyway)
* Click START
This worked for me and meant that I now have CWM Manager v3.60 running without the warning "this version of CWM Manager should be used with CF-CWM .1.1 or newer. It appears that you are running a different recovery. Various features have been disabled."

5.5.4.8 Touch works ok, dunno about mounting external, though. The none-touch that comes with CF-CWM works ok.
One question : Why you terribly require to mount the SD card from Clockworkmode??? since you have other options to tranfer your files to SD card.
I dont think you can mount even on the Cainfire's CWM, since SGS3 is not supporting to mount SD cards as mass storrage even booted condition.
Thanks SwiftSmoke, Kryten2k35 & ZACQ8 for the help!! much appreciated!!!
I have gotten myself terribly confused with all this although the 'mist' is now starting to lift a wee bit now
I have the premium version of the following CF apps - Rom Manager (CW Manager v3.60); Mobile Odin Pro v3.0; Triangle Away v1.70 and ROM Manager Premium v5.5.58 (CWM 6.0.1.0)
I have 'rooted' my mobile and successfully run 'Triangle Away'.
All my problems began when I tried to change my mobile from 'stock' ROM to a Cyanogen ROM (I downloaded a stable v9 Cyanogen ROM and placed it onto the root of my external SD card. All my problems then began when I rebooted CWM v3.60 into Clockwork Recovery mode to find out that it would not recognise my SD card).
I have now successfully applied CF-SGS3-CWM-v5.5-v1.5.zip.
Question: what is the simplist way to flash to Cyanogen from here? Can I download a ROM and simply use Mobile Odin from now on?
Thanks again for your patience .. I joined XDA way back in 2006 so im disappointed my skills are not up to much at the moment (like many many others I got seduced by the Big Apple!!)
Bob
dont use ROM Manager anymore with this CWM (CF)
use Vol-up+Home+power to enter CWM
you should be able to see now external SD, choose your CM9 zip file from
'install zip from SD card' / 'choose zip from SD card' then, you will find the zip,
if not your SD card is not supported, reeboot and place the zip on the internel SD card through MTP
then select the zip from "choose zip from internel SD card"
dont forget to do the other steps (wiping cache. dalvik etc.. as per the ROM thread instruction)
Thanks ZACQ8 - that is exactly the advice I need
I'll post back later as to how I get on so that anybody else with my problem can follow this through.
Bob
All sorted!
I have now got my mobile running CM9.0 RC2
What I didn't realise was that you can access both your internal and external SD card via the Kies app (it works on both OS X and Windows PC when connected by USB cable).
During the reboot my mobile automatically detected that I am on a UK/O2 sim (I wasnt too sure if it would and was initially put off changing the stock ROM thinking it would cause problems - it didnt and hasnt!!)
Thanks to all who helped!!

Any idea why that is? I'd like to use my sdcard the same way as any htc did, using TotalCommander and seeing it as an external drive. I had all sorts of backup and sync-scripts working with my htc, now they are all useless, because of this stupid restriction.
I guess I'll wait for someone to crack through this silly wall created by Samsung.
And I see some have already done the first part (external sdcard as USB drive) : http://forum.xda-developers.com/showthread.php?t=1711009
I have same problem with Sandisk 64GB, I have installed Recovery from HERE, still not working, I did not try format SD through recovery yet, maybe problem is Recovery does not support ExtFat system which is on 64gb, but 32GB sd card work fine with out any extra manipulations, it has Fat32 on it.
Any idea why that is?

Lots of technical reasons. With a running phone you can use the APK 'Easy UMS' to mount the sdcard as mass-storage anyway.
You _should_ be able to run the commands manually through adb in CWM.

I also have same problem/error with my Sandisk 64GB. Running latest version CWM 6.0.2.3 on rooted Stock ROM T-mobile GS3.
I would really like to save/backup/restore my nandroids from the ext_sdcard since they are over 2GB....on a 16GB internal space is more than I have to spare. Can anyone confirm a fix or workaround for this? Thanks in advance.
**UPDATE**
So it appears the problem is ExtFat is the problem...is there a way to format a 64GB card with FAT32? from what I have read on other threads using windows or the phone itself will use the EXTFat format.
**UPDATE 2** found another XDA thread with the fix found here:

I tried the Fat32 format and I was able to format the SanDisk Mini SD 64gb to Fat33; however, CWM still won't recognize the ext SD. Were you successful in any way? I May just downgrade from 6.0.2.3 to the 5's as mentioned in another thread, but I have to refind it. I'll update once I confirm that the ext SD will in fact in CWM.

I just found out I have the same problem. I am about to follow these steps but apparently it's inside the S3 thread.
Can I use this method for my Note 2 N7105?
I had the same problem on my Note II N7105 with ClockworkMod 6.0.3.2 and a 64GB SanDisk.
I backed up my SD card, then used this tool to format it to FAT32 on my Win7 Laptop: http://www.ridgecrop.demon.co.uk/ind...at32format.htm
After that I copied everything back. Works perfectly now. Thanks Rafi_ for pointing me in the right direction.
I've got SanDisk Ultra 64GB microSDXC formatted FAT32 with 32K cluster size and CWM 6.0.3.2 can't mount it. Installed PhilZ Touch 5, which is also based on CWM 6.0.3.2 and same issue.
Also can't read the contents in SlimBean or LiquidSmooth. It works fine in FoxHound, OmegaROM and Sotmax. My 8GB microSD works fine everywhere.
Any ideas why I'm not having the luck with this 64GB card with FAT32 format and 32K cluster size?

[RECOVERY] ClockworkMod Touch 6.0.1.0 cant recognise my sd card

How come i cant back up to external sd card. it says it cant mount backup path. i got a 64gb sdxc card class 10. i thought this version supported external sd card
im using a uk unbranded s3 on stock samsung firmware
do i have to format and partition the sd card using cwm first and then try to backup to sd card. the sd card as of now is ex-fat
Exactly the same problem here, installed CWM touch and it can't recognise my 16GB card, 8GB or 2GB. I reckon its because samsung have named it Exsdcard or something like that instead of emmc or whatever its meant to be.

I already had a thread like this one
http://forum.xda-developers.com/showthread.php?t=1798262
This was my ONLY solution...
1. I RE-Rooted with CF Root 6.4
( it installs CWM 5.5.0.4)
Everything perfect....
BUT if I try to Upgrade CWM 5.5. --- to --- 6.0
Then I have the MOUNTING PROBLEM
So I have to (ONLY) :
1. Re-Root again with CF Root 6.4
And Everything goes back to NORMAL...
yep exactly. only way is to use CF-root and that cwm mod works on the micro sdxc card. eff the touch version
Well the touch version works very well for me. It shows the sdcard and external sdcard so I am at a loss as to why yours does not work. I have the international version and on the omega v10 rom.
I am having a similar problem. External SDcard is no longer recognised for me on ANY touch version.
Had no trouble on non touch one that came with omega under v10. I installed CWM touch through rom manager on Omega v9, when I upgraded to v10 the CWM stayed the same. Then messing about some more seeing which version I prefered I ended up installing a few versions before settling with Rom manager touch version.
At the beginning, first use of CWM touch, external card mounted fine and could backup to it. Somewhere between then and now I have lost the ability to mount sdcard.
I have performed full wipes of everything and reinstalled numerous times but no matter what I do now, CWM touch will not load extsdcard.
My theory is there must be some config file or something somewhere that needs to be deleted that is stopping CWM touch from properly choosing the correct path. If it's not that, then I have no clue wt* is going on.
EDIT: Know I could just use the non touch version, but I prefer the blob backup system, could care less about the touch feature personally.

[Q] What to do if I lost access to my internal storage as well as sd card

Hi, new guy with english problems here, be gentle
So basically I lost access to any kind of storage on my SGS2 running CM10.1. Here's what happened. I was using internal and sd for a long time, then, as I needed my SDHC elsewhere i removed it. Nothing was lost as all data was stored internally. BUT. After formatting SD in FAT32 and putting it back everything crashed. Apps are refusing to work, demanding an SD card. Files Manager says that folder was lost. All of them. First thing I wanted to do was to flash CM once again, a newer NB but my PC does not read internal storage either, and putting it in sd doesn't do me any good as cwm doesn't see it also. CM can access internal, so i flashed the same version of CM once again - the only one i got there. Nothing changed. I'm a bit lost and seek any advice
U checked if u really format it with Fat32?

Sure. Also I formatted it with SDFormatter, thanks to this CWM can mount it and format by itself, but OS does not respond anyway

Thank you! That was the problem

CWM 6.0.2.7 - 64 GB ext SD card, Unable to mount / format / access, etc.

Hi there,
I have the following issue and hope to find somebody with a solution here in the XDA-world...would be great.
Of course I did some searching before I post here, but the results are not sufficient for me...
I am using a 64 GB external SD card in my Samsung Galaxy S III since a few days. Before I put data to the card, I performed a format via the phone itself. The access works great - I can use all my files when I use the phone in normal operation. (with Ultima Rom).
Today I downloaded the latest ROM release and wanted to flash it via CWM 6.0.2.7 and I encountered a problem - I cannot access the external SD card in CWM recovery. It simply say´s "Can´t mount external SD".
Why is it? Any solution proposals? I used to have a 2GB card and the installations worked fine with CWM here....
Is it a wrong formatting probably? Or the size?
Thanks for any suggestions!!!
You should do some search before post, but since you are here, I give you some briefly information, but you have to search more details yourself.
1. 64 GB sdcard is formated in exFAT file system which CWM recovery doesn't support it, that's why you have problem with 64 , but OK with 2GB sdcard. (Some latest recovery has now support exFAT I think )
2. Solution, format your sdcard into FAT32 file system, or change to 32 GB sdcard because unless you have countless files or blue ray movies otherwise you won't need 64GB at all, that's what I did, I had 64 and change to 32 to avoid any kinda potential problem

1. Use PhilZ Touch recovery (based on 6.0.2.8 - I think 6.0.2.7 was also very buggy - and with a new Samsung kernel supporting exFAT).
2. Format as FAT32.
I am currently using the 1st approach, but keep in mind that many ROMs (mostly based on CM10 stuff) still have a huge bug where the exFAT partition is not recognized but instead some stuff is written to the first sector - when that takes place just put the exFAT card in a SD-reader in Win7/8, reject any suggestion to format it and then from the command line run CHKDSK /F Letter:
Thank you!!!
Thanks a lot to both of you!!! It worked out! :highfive:
I also managed to search for "how to format an SDCard to FAT32", no problem.
To be honest I also had a look for a possible solution like you suggested prior to my post --> I just was not confident that these suggestions will solve the issue since I read many times "tried - but no success"...
I just wanted to be sure, coming back from work, not to spend hours to solve it, if you already have "the one working" solution available. Once again many thanks - I really appreciate this community, even if its my 2nd active post...
